Tax form PP 36 is the Valude Added Tax (VAT) return that the company files on behalf of its overseas suppliers. Because overseas suppliers are not registered in the Thai VAT system, when the company makes payment to them, it has to submit 7% VAT on behalf of them. The VAT amount will become the company’s input tax (thus can be claimed back) in the month that the company submits it.

Within the 15th of the month, file the monthly Valude Added Tax (VAT) return (PP 30) with the Revenue Department. This form summarizes the input and output VAT of the previous month and it has to be filed even if there are no transactions.
